how many hours?

I have a 3- 100 watts panels, a 40 amps rover controller and a 100ah lithium phospate battery. I run a dometic fridge- freezer that use 5.6 amps, I know this information because I also have a trimetric meter in my sistem. My question is how many hours my fridge should run with my 100ah battery? Also how come the bigger number that I see in my rover and trimetric meter is 13.1 volts with the battery fully charged ? It is supposed to be like 14. something?

use your trimetric to determine how many ah it uses in 24 hrs and compare to battery bank.I assume it uses ~6A while operating but how much does it actually run, consider how often the door is open and the ambient temperature.

A model # might be helpful if dometic has measured daily or annual energy use

You'll need to contact support about the voltage, I have questions of the Li charge profile. Once it reaches charging voltage what is the charge profile, there is no state time or float v, so does it stop charging till the voltage is below the return to boost voltage?

It goes to float after reaching 13.1 volts. The trimetric meter shows tha is using 5.6 amps. I left it running last night and I didn't last. This morning the sistem was death.I think something is wrong. After paying $865.00 for this battery I thought that it would work for more than a few hours.

You need to buy a Kill-A-watt meter.... But a 100ah battery isn't very much.... Like your finding out I really doubt that you can run a fridge all night.. It's a guess because more info is needed I would think that you will need at least 400ah of battery to besafe....

I myself don't like Li batteries... They are way to expensive for the amount of power that you get...... I have way less than $865.00 in my 6, 645ah of batteries.....

This sistem is in a vw bus,so the weigh of the battery is crucial. The dometic fridge use 5.6 amps, I can see that with my trimetric meter. Why do I need a kill a watt meter?

The only thing that I have running is the dometic fridge using 5.6 amps?

Because it will tell you how many watts your using in a 24 hour period something that your T meter doesn't tell you..... All it tells you is what the draw is not run time etc...... Things you really need to know....

I looks like you spent a lot of money on your solar system and I can understand your frustration...... But I still say your battery is to small for what your trying to run off of it............

Both AC and DC.

Ok thanks, I'm ordering another battery today, but I still want to know why is not charging pass 13.1 volts. I really appreciate your help guys.

So why is not charging fully? It stays at 13.1 volts all the time, even after a week of full sun with nothing connect it to it.

For verification purposes, you are on the lithium charging profile correct?

A description of my solar sistem is in the beginning of the tread and yes the dometic fridge is ac and dc it does recognize what kind of power is connect it to. I guess it has some kind of transfer switch inside.

It can't be running on both...... It's one or the other.... What size inverter do you have.....

Tell us what you have in your solar setup and don't leave anything out......

I guess it has some kind of transfer switch inside. I do not use the power inverter for the fridge. The fridge is connect it directly to the battery.

I'm at work now. It should be charged when I get home, but like I said before, just to 13.1 volts. I thought it was normal I have been using it like that for a year but last night was the first time that I run the fridge completely on solar for that long. That's how I noticed that something is wrong.

I have a 3- 100 watts panels, a 40 amps rover controller and a 100ah lithium phospate battery. I run a dometic fridge- freezer that use 5.6 amps, I know this information because I also have a trimetric meter in my sistem. My question is how many hours my fridge should run with my 100ah battery? Also how come the bigger number that I see in my rover and trimetric meter is 13.1 volts with the battery fully charged ? It is supposed to be like 14. something?

Do you have an inverter or is everything running DC? If it's DC is it connected to the load side of the CC or is it connected to the battery? What size battery cables do you have? Do you have any fuses in the system?

Now were getting some where......

So how and what did you have it hooked to before last night for it to be working so long? How do you know that the voltage is at 13.1 all the time it never drops down? It could be stuck in float mode?

Since I was rudely interrupted by bird, Can you tell us more of what you have in your system.....

The only thing that I run with the solar is the Dometic fridge. Tha cables are the ones that cane with the 300 amps kit. Yes I do have fuses in the sistem. The guys from Renogy think that the problem is my battery. They also told me tha I should be able to run the fridge for about 15 hrs.

What was the voltage in the battery this morning?

So many questions but I will wait on bird to again answer them.......

I now that the voltage is 13.1 because I can see it on the screen of my Rover controller and also on my trimetric meter. The 13.1 volts drop down when I using the battery to power the fridge but when is charging the voltage never goes over 13.1 volts and tha is my concern. This morning everything was off. When I got home from work today the voltage was at 12.1

Did Renogy think that the battery was the problem with why it won't get above 13.1v..........

So you don't have an AC inverter? Everything is DC? Is your fridge hooked to the load side of the CC or the battery?

What did you have hooked to the system last night before you had the problem? You know when everything was running ok?

Yes, renogy thinks tha the problem can be the battery. They said that I should see 14.6 volts in my rover screen. There's an inverter but the fridge is not connect it to it. I have not use it once. I keep it off. The only thing connect it to the sistem is the Dometic fridge. I just notice the problem because last night was the first time that I left the fridge running using the battery. When I'm not using the bus, she's connect it to the house power like an RV. When I disconnect the cord from the bus the fridge reconize the change and starts working on DC. When I plug the cord the fridge change from DC to AC. All this automaticly.

Now that is really cool.... I know the fridge switches back and forth from AC to DC...... But is there a device you have that the fridge is hooked to that allows you to hook it up to and it switches back and forth from AC to DC on it's own or do you have a switch? Or is the AC hooked up to a battery charger....

Sorry for so many questions but I'm trying to learn what kind of system you have.... It sounds interesting....

The fridge has two cords. One is connec it to the battery and the other one to a braker box inside the bus. I also have a 3000 watts honda generator on the back bumper. The generator and house power are connect it to an automatic transfer switch. I use the generator when bundoking to run the roof ac, cooking pan and to make coffee.

Man that sounds like an awesome setup you have there.... Thanks for explaining it...

Ok the friking problem was the Rover controller since new.It was stockon float mode. I installed a new Victron controller along with a battery monitor and boom 14.6 every day. The Dometic just use 22% of the battery power overnight. The battery is back to 100% by 10am. I knew one battery should be enough for what I'm doing, specially after spending a little fortune in it.

Thanks for the follow up, can I assume 22% is for 8hrs and that for a full day ~70% of your 100ah li battery?

Is a 170ah battery. The Dometic is running 24/7, during the day it runs from the solar panels and the battery is fully charged by 10am. When the sun goes down it starts using the power from the battery. I check the % of the battery every morning around 5AM and is at 78%. It does run more than 8 hours on battery power, about 11 hrs.

It sounds like your system is running just fine.... But the % of the battery is useless...... What is the battery voltage in the morning?

I don't have the trimetric anymore. I find out that Victron has way more modern technology. I can monitor the entire system with my phone. Batteries, panels, power inverter, transfer switch and charger. All the information is sent to my phone via bluetooth. The only thing I'm keeping Renogy is the batteries, panels and DC to DC charger. Everything else is been replaced with Victron components.
